Features, pricing, ratings, and pros & cons — compared head-to-head.
Owl DiOTa is a commercial operational technology network segmentation tool by owl cyber. Sphyrna NGXS UGW-200 is a commercial operational technology network segmentation tool by Sphyrna Security. Compare features, ratings, integrations, and community reviews side by side to find the best operational technology network segmentation fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise OT teams managing critical infrastructure will get the most from Owl DiOTa because hardware-based data diodes are the only enforcement mechanism that actually prevents exfiltration, not just monitors it. The compact form factor means you can deploy it at distributed OT boundaries without ripping out existing networks, and minimal maintenance keeps your already-stretched OT staff from babysitting another appliance. Not the right fit if you need east-west microsegmentation across a sprawling OT fabric or if your governance team demands software-based solutions that play nicely with existing IT security stacks.
Enterprise and mid-market security teams protecting industrial control systems or classified networks from data exfiltration need the Sphyrna NGXS UGW-200 because its hardware-enforced unidirectional gateway eliminates the attack surface that traditional firewalls leave open. NSA approval plus Common Criteria EAL 4+ certification, paired with 20Gbps maximum throughput over 25Gbps interfaces, means you're getting speed without sacrificing the cryptographic assurance that regulators actually care about. Skip this if your threat model is application-layer attacks or you need bidirectional control; unidirectional gateways are a hard architectural choice that only works when one-way data flow matches your actual use case.
